   While much of it is indeed the fault of the protocol, a good deal of blame
should be laid on an operating system which permits any user running any
program to access any device in any way.  The operating system should provide
user authentication and not permit untrusted users to put the ethernet card
in promiscuous mode.  For any installation with multiple machines and 
networks, this is the case.
